不同人工湿地填料对水体中总磷的吸附特性分析
The Phosphorus Adsorption Characteristics of Different Fillings in Artificial Wetland
摘要
Abstract
In this study, the phosphorus adsorption characteristics of four fillings included slimy shale, black shale, honeycomb cinder and river sand which were used in the constructed wetland were studied by isothermal adsorption experiment and adsorption kinetics experiment. The results of the isothermal adsorption experiment showed that the phosphorus adsorption capacity of the four fillings increased as the initiative concentration of the phosphate increased, and the phosphorus adsorption capacity of slimy shale and honeycomb cinder was much larger than that of black shale and river sand. In the experiment of adsorption kinetics, the results of the curve indicated that the characteristics of the phosphorus adsorption kinetics in the four kinds of fillings were the same. At the beginning time the phosphorus was absorbed very fast in the different fillings and then slow down until the adsorbance reached the adsorption equilibrium. The order of the phosphorus adsorption capacity in the four fillings was that honeycomb cinder > slimy shale > river sands > black shale. The results indicated that the efficiency of honeycomb cinder and slimy shale were much better than that of the other two fillings when being used in removal phosphorus.关键词
